Form factors are nonperturbative objects. Therefore, in order to study form factors, one needs to use a non-perturbative method. QCD sum rules is one of the nonperturbative methods. It is an analytical method which is directly based on the QCD Lagrangian.
It is a powerful tool to extract hadron properties [1]}, [2]}, [3]}, [4]}.
Using this method static (e.g. baryon masses) and dynamic (e.g. magnetic moments and coupling constants)
hadronic parameters can be determined.
An alternative to the traditional QCD sum rules is the
light cone QCD sum rules (LCSR). LCSR is especially suitable to study the interactions of hadrons at large momentum transfer [5]}, [6]}, [7]}.
In LCSR, the hadronic properties are expressed in terms of the properties of the vacuum and the light cone distribution amplitudes of the hadrons in the process.
Since the form factors are expressed in terms of the properties of the QCD vacuum and
the distribution amplitudes, any uncertainty in these parameters reflects in the uncertainty of the predictions of the form factors.
This method has been rather successful in determining hadron form factors at high \(Q^2\)  (see e.g. [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}). Using the LCSR, the isovector axial vector form factors of octet baryons have been calculated [13]}.
For \(\Delta \)  baryon isovector axial vector and pseudoscalar form factors have been studied
using lattice QCD [16]},
chiral perturbation theory [17]} and
quark models [18]}, [19]}, [20]}, [21]}.
